[Non-palpable testicle: joint review of pediatric endo-surgical group and its management by laparoscopy]

We present the joint serie of 5 Pediatric Centers with 256 patients diagnosed of cryptorchidism with nonpalpable testis treated by laparoscopy. We have found that Ultrasound examination is not very useful. This entity affects more to the left side 60%. In near half of the cases 46% we have not found any testicle and in 54% it was carried out an orquidopexy by different methods. In 27% we made an orquidopexy by Fowler-Stephens technique with 86% of good results. We think that laparoscopy is the best way of diagnosis and treatment of this patients.
